ABSTRACT:
The present invention provides a rubber composition for a tire that is capable of improving air permeability resistance while preventing chipping of the bead toe and a pneumatic tire comprising the rubber composition. Specifically, the present invention relates to a rubber composition for a tire containing a composite material comprising rubber, polyolefin and nylon; the composite material being contained so that the content of nylon is 1 to 40 parts by weight based on 100 parts by weight of the total rubber component in the rubber composition.
